although, grapevines do not have a high chilling requirement, its fulfillment is critical for normal development of the vines. in tropical and subtropical regions such as farrashband, in the south of iran, there is no adequate winter chilling to release bud dormancy in grapevines. so it is necessary to consider the effect of chemical dormancy–breaking agents on bud dormancy. in the present rese...

abstract dormancy in potato minituber buds is one of the limiting factors on planting them after harvesting. this study was undertaken in a completely randomized nested with arrengment three replications to examine the effective hormonal and temperature treatments on rapid breaking of minitubers dormancy at 2008. treatments included gibberellic acid (2 and 5 mg/l), benzyl adenine (5 and 10 mg/l...
to study the effects of chilling on dormancy breaking and the increased germination characteristics of nepeta (germination percent and speed, seedling length, vigor index, wet and dry weight), a factorial experiment in a completely randomized design with 4 replications was implemented in a laboratory in 2014. factor a was the chilling treatment in three levels (control, one-month and two-month ...
DOR: 98.1000/2383-1251.1397.5.55.9.1.1603.41 Extended abstract Introduction: Malva (Malva neglecta) is one of perennial plants of the Malvaceae family. One of the most important mechanisms for survival of the plants is dormancy, rest or distance in germination and growth; in this case, despite favorable conditions for germination, the seed remains at rest for an indefinite period of time....
Extended Abstract Introduction: Galbanum is one of the most important native medicinal plants in Iran, and nowadays the use of its products and derivatives has become widespread in various industries. Thus, the excessive harvest of this species within its natural habitats has increased. Therefore, the species is enlisted as prone to extinction. Due to the lack of information about germination ...
galbanum (ferula gummosa bioss) is a medicinal, commercial and industrial plant in iran but its cultivation is restricted by seed dormancy. therefore, a study was conducted to determine class and environmental requirements for breaking of seed dormancy. during imbibition study, both scarified and intact seeds exhibited similar pattern in water uptake and it seems there is not physical dormancy....
In order to investigate different treatment effects on germination in Gundelia tournefortii, three factorial experiments were carried out in the completely randomized design with three replications. The first factor was stratification at 4oC in three levels including 0, 3 and 6 weeks, the second factor was mechanical scarification in two levels including seeds with/without scarification and the...
Coffee seeds take a long time to germinate, as the tough seed coat can cause dormancy. This is because water absorption and gas exchange are disturbed mechanical barrier. Breaking of dormancy maximize germination needs be done before sowing seeds. The aim this study was obtain an appropriate effective soaking agent for breaking Kerinci arabica coffee research conducted using Randomized Block De...
